Description

Technisches Gebiettechnical area

Die Erfindung befaßt sich mit einem Reinigungstuch in Vliesstruktur zur Naß-, Feucht- und/oder Trockenreinigung.The invention is concerned with a cleaning cloth in fleece structure for wet, damp and / or dry cleaning.

Reinigungstücher sind allgemein bekannt und dafür vorgesehen, Schmutz von der Oberfläche eines Gegenstandes abzulösen und selbst aufzunehmen. Um beide Aufgaben zu lösen, muß ein Reinigungstuch eine sehr gute Reinigungsleistung sowie eine ausreichende Abriebfestigkeit haben und über ein ausreichendes Porenvolumen verfügen, um den Schmutz zu speichern.Cleaning wipes are well known and intended Dirt from the surface of a To detach the object and record yourself. To solve both tasks, a cleaning cloth must be a very good cleaning performance and sufficient abrasion resistance have and about a have sufficient pore volume, to store the dirt.

In der DE 30 35 038 A1 wird ein Reinigungstuch behandelt, welches gute Gebrauchseigenschaften aufweist. Es besteht aus porösen Mikrofasern aus einem polymerem Werkstoff, die einen im wesentlichen porenfreien Faserkern und einen offenporig geschäumten Fasermantel aufweisen. Ein solches Reinigungstuch aus polymerem Werkstoff hat eine besonders hohe mechanische Widerstandsfähigkeit, was sich positiv in bezug auf die Beständigkeit gegen Abrieb auswirkt. Durch eine Vermischung von Mikrofasern mit Stapelfasern oder Endlosfasern wird eine verbesserte Sprungelastizität und eine vergrößerte Fülligkeit mit verbessertem Schmutzaufnahmevermögen erreicht.In the DE 30 35 038 A1 a cleaning cloth is treated which has good usage properties. It consists of porous microfibers made of a polymer material, which have an essentially non-porous fiber core and an open-pore foamed fiber jacket. Such a cleaning cloth made of polymeric material has a particularly high mechanical resistance, which has a positive effect on the resistance to abrasion. By mixing microfibers with staple fibers or continuous fibers, improved elasticity and increased bulkiness with improved dirt absorption capacity are achieved.

Eine andere Ausgestaltung eines Reinigungstuchs ist in der US 4 145 464 behandelt. Dort wird das Reinigungstuch aus einem Gemisch aus Zellulose- und Synthesefasern hergestellt, das beiderseits durch zellulosische Schichten abgedeckt ist und durch eine gegenseitige Verklebung sämtlicher Fasern in örtlich getrennten Bereichen verfestigt ist. Ein solches Reinigungstuch hat jedoch keine ausreichende mechanische Festigkeit, da die Zellulosefasern eine relativ geringe Länge von unter 6,35 mm haben, wodurch in der Folge eine unbefriedigende Abriebbeständigkeit entsteht. Schon nach relativ kurzem Gebrauch kann es zur Ablösung von Faserbestandteilen kommen, die sich in Gestalt von staubförmigen Partikeln oder Fusseln auf der zu reinigenden Fläche niederschlagen.Another embodiment of a cleaning cloth is in the US 4,145,464 treated. There, the cleaning cloth is made from a mixture of cellulose and synthetic fibers, which is covered on both sides by cellulosic layers and is solidified in a separate area by mutual bonding of all fibers. However, such a cleaning cloth does not have sufficient mechanical strength, since the cellulose fibers have a relatively short length of less than 6.35 mm, which results in unsatisfactory abrasion resistance. After a relatively short period of use, fiber components can become detached, which form dust-like particles or lint on the surface to be cleaned.

Durch die EP 0 423 619 A1 ist desweiteren ein Reinigungstuch bekannt, welches aus mehreren Schichten gebildet, ist und zwar aus einer Schicht aus synthetischen Endlosfasern, sogenannten Filamentfasern, die mindestens auf einer ihrer Seiten eine Schicht aus Stapelfasern vermischt mit natürlichen Fasern hat. Die Menge an natürlichen Fasern wird mit 15 bis 70 % angegeben. Bei diesem Reinigungstuch wird eine hohe Festigkeit erreicht, insbesondere durch die Unter- oder Mittelschicht aus synthetischen Endlosfasern. Jedoch führen die kurzen natürlichen Fasern in der beziehungsweise den Deckschichten zu einer unbefriedigenden Abriebfestigkeit ähnlich, wie bei der voranstehenden US 4 145 464 .Through the EP 0 423 619 A1 a cleaning cloth is also known, which is formed from several layers, namely from a layer of synthetic continuous fibers, so-called filament fibers, which has a layer of staple fibers mixed with natural fibers on at least one of its sides. The amount of natural fibers is given as 15 to 70%. This cleaning cloth achieves a high level of strength, in particular through the lower or middle layer made of synthetic continuous fibers. However, the short natural fibers in the top layer (s) lead to unsatisfactory abrasion resistance similar to the one above US 4,145,464 ,

Durch die EP 0 080 383 A2 ist ein Reinigungstuch aus Mikrofasern bekannt geworden, dass mit Öffnungen auf seiner Fläche versehen ist, um darin ein Fluid aufzunehmen. Die Öffnungen betragen 1 bis 40% der Oberfläche. Ein solches Wischtuch hat den Nachteil, dass die Öffnungen durch Schmutzteile sich sehr bald zusetzen, so dass das Tuch sehr schnell seine Wirksamkeit bezüglich einer Wasseraufnahme verliert.Through the EP 0 080 383 A2 has become known a cleaning cloth made of microfibers, which is provided with openings on its surface to receive a fluid therein. The openings are 1 to 40% of the surface. Such a wipe has the disadvantage that the openings become clogged with dirt very quickly, so that the wipe very quickly loses its effectiveness in absorbing water.

In der EP 0 357 496 A2 wird ein Wischtuch beschrieben, das aus polymerem Mikrofasern und Zellulosefasern besteht, und das mit einer synthetischen Reinigungsflüssigkeit imprägniert ist. Tücher dieser Art, verlieren schnell an Wirksamkeit da die Reinigungsflüssigkeit sehr schnell aus dem Tuch entweicht.In the EP 0 357 496 A2 describes a wipe that consists of polymeric microfibers and cellulose fibers and that is impregnated with a synthetic cleaning fluid. Cloths of this type quickly lose their effectiveness because the cleaning liquid escapes from the cloth very quickly.

Ein aus nicht-elastischen schmelzgeblasenen Fasern und anderem Fasermaterial gebildetes Faservlies wird in der DE 8916164 U1 beschrieben, bei dem die schmelzgeblasenen Fasern hydraulisch mit dem anderen Fasermaterial verschlungen sind. Das andere Fasermaterial kann aus Zellstofffasern, Stapelfasern oder anderen Fasern ausgewählt werden. Wegen seiner Steifigkeit ist dieses Vliesmaterial eher für eine Schutzbekleidung, als für ein Wischtuch geeignet.A nonwoven fabric formed from non-elastic meltblown fibers and other fiber material is used in the DE 8916164 U1 described, in which the meltblown fibers are hydraulically intertwined with the other fiber material. The other fiber material can be selected from cellulose fibers, staple fibers or other fibers. Because of its stiffness, this nonwoven material is more suitable for protective clothing than for a wipe.

Vliese die aus schmelzgesponnenen thermoplastischen Mikrofasern und mindestens einer weiteren Faserschicht bestehen, können den europäischen Patentanmeldungen EP 0 333 212 A2 und EP 0 569 860 A1 entnommen werden. Nonwovens made of melt-spun thermoplastic microfibers and at least one additional fiber layer can be used for European patent applications EP 0 333 212 A2 and EP 0 569 860 A1 be removed.

Der Erfindung liegt die Aufgabe zugrunde, ein Reinigungstuch für Naß- Feucht- und/oder Trockenreinigung zu schaffen, das eine hohe Abriebfestigkeit hat sowie ein großes Aufnahmevolumen für den abgeriebenen Schmutz aufweist. Es soll außerdem möglichst fest sein, eine gute Reinigungsleistung bringen und darüber hinaus angenehm im Griff sein.The invention is based on the object Cleaning cloth for Wet, damp and / or dry cleaning to create that has a high abrasion resistance and a large volume for the has rubbed off dirt. It should also be as firm as possible, a good one Bring cleaning performance and also be pleasant to the touch.

Die Lösung der gestellten Aufgabe wird bei einem Reinigungstuch der eingangs genannten Art erfindungsgemäß dadurch erreicht, daß das Reinigungstuch aus Mikrostapelfasern aus mindestens zwei verschiedenen Polymeren und aus saugfähigen im Spinnvertahren hergestellten Sekundärstapelfasern besteht. Bei einem solchen Reinigungstuch wird die hohe Reinigungsleistung und Festigkeit der Mikrostapelfaser und ihre Abriebfestigkeit mit der hohen Saugfähigkeit der Sekundärstapelfasern kombiniert. Die Sekundärstapelfasern werden in die Mikrostapelfasern eingebunden und darin sicher gehalten.The solution to the task is thereby according to the invention in a cleaning cloth of the type mentioned accomplished that Micro-staple cleaning cloth made from at least two different Polymers and absorbent im Secondary staple fibers produced by spinning. at Such a cleaning cloth is the high cleaning performance and Strength of the micro staple fiber and its abrasion resistance with the high absorbency of the secondary staple fibers combined. The secondary staple fibers are integrated into the micro-staple fibers and held securely in them.

Bei den Mikrostapelfasern handelt es sich um Mehrkomponenten-Splittfasern, insbesondere um Bikomponenten-Splittfasern. Sie werden überwiegend aus Polymeren auf der Basis von Polyester und Polyamid gebildet. Hier besteht ein weites Feld möglicher Varianten. Die Auswahl der Splittfasern oder Spaltfasern erfolgt hier vorzugsweise unter ökonomischen und verfahrenstechnischen Gesichtspunkten.The micro-staple fibers are multi-component split fibers, in particular bicomponent split fibers. You will be over mainly made of polymers based on polyester and polyamide. There is a wide range of possible variants here. The selection of the split fibers or split fibers is preferably carried out from an economic and procedural point of view.

Der Titer der Mehrkomponentenfasern liegt vor ihrer Splittung bei 1,7 bis 3,0 dtex. Der Titer der Splittfasern liegt unter 1 dtex, vorzugsweise unter 0,2 dtex.The titer of multi-component fibers is 1.7 to 3.0 dtex before splitting. The titer of the split fibers is less than 1 dtex, preferably less than 0.2 dtex.

Als Sekundärstapelfasern werden aus Naturfasern, insbesondere aus im Chemiefaser-Spirroverfahren hergestellte Fasern aus Viskose, Lyocell hergestellte Stapelfasern verwendet. Der Titer der Sekundärstapelfasern liegt bei 1,0 bis 3,0 dtex. Diese ersponnenen Stapelfasern sind bedeutend fester, als übliche Naturfasern.As secondary staple fibers from natural fibers, in particular from fibers produced in the chemical fiber spiro process Staple fibers made from viscose, lyocell are used. The titer of the secondary staple fibers is 1.0 to 3.0 dtex. These staple fibers are spun significantly firmer than usual Natural fibers.

Um ein möglichst großes Porenvolumen zu erreichen, ist es günstig, wenn das Reinigungstuch aus mindestens zwei übereinanderliegenden Vliesschichten gebildet wird. Dabei ist es besonders günstig, wenn eine der Vliesschichten aus Mikrostapelfasern und saugfähigen Sekundärstapelfasern besteht und die andere Vliesschicht aus polymeren Tertiärstapelfasern, insbesondere aus einem Thermoplast und saugfähigen Sekundärstapelfasern gebildet ist. Diese unter Einsatz von Tertierstapelfasern hergestellte Vliesschicht ist besonders voluminös. Hier wird somit die hohe Reinigungsleistung und Abriebfestigkeit der Mikrostapelfasern auf der einen Seite des Reinigungstuches in Verbindung mit dem besonderen Volumen der Tertiärstapelfasern und der Sekundärstapelfasern auf der anderen Seite des Tuches ausgenutzt. Das Saugvermögen wird durch die Sekundärstapelfasern erhöht. Die besonders bevorzugte Ausführungsform sieht vor, eine Vliesschicht aus polymeren Tertierstapelfasern und saugfähigen Sekundärstapelfasern als Mittelschicht zu nehmen, die auf ihren Seiten jeweils von einer Deckvliesschicht aus Mikrostapelfasern und saugfähigen Sekundärstapelfasern eingefaßt ist. Bei diesem Reinigungstuch haben die beiden äußeren Schichten, die mit dem zu reinigenden Gegenstand in Berührung kommen, eine hohe Abriebfestigkeit, während die Mittelschicht ein besonders starkes Volumen mit einer hohen Saugfähigkeit hat. Als Tertierstapelfasern kommen vorzugsweise Stapelfasern aus einem Polyamid zum Einsatz, mit einem für solche Fasern üblichen Titer, der über dem Titer der Mikrofasern liegt.In order to achieve the largest possible pore volume, is it convenient if the cleaning cloth consists of at least two superimposed layers of fleece is formed. It is particularly advantageous if one of the fleece layers made of micro-staple fibers and absorbent Secondary staple fibers and the other non-woven layer consists of polymeric tertiary staple fibers, in particular from a thermoplastic and absorbent secondary staple fibers is formed. This is produced using Tertier staple fibers The fleece layer is particularly voluminous. So here is the high one Cleaning performance and abrasion resistance of the micro staple fibers one side of the cleaning cloth in connection with the special Volume of the tertiary staple fibers and the secondary staple fibers exploited on the other side of the cloth. The pumping speed is through the secondary staple fibers elevated. The particularly preferred embodiment provides for a nonwoven layer made of polymeric Tierier staple fibers and absorbent Secondary staple fibers to be taken as a middle class, each of them by one Cover fleece layer made of micro-staple fibers and absorbent secondary staple fibers bordered is. With this cleaning cloth, the two outer layers that have the object to be cleaned come, high abrasion resistance, while the middle layer has a particularly strong volume with a high absorbency. As tertiary staple fibers preferably staple fibers made of a polyamide are used, with one for such fibers usual Titer that over the titer of microfibers.

Die bevorzugte Herstellungsart eines Tuches aus mehreren Vliesschichten sieht vor, zunächst einzelne Vliesschichten zu bilden und dieselben miteinander zu verbinden. Dabei kann jede Vliesschicht mit den Sekundärstapelfasern bereits versehen sein. Es ist aber auch möglich, zunächst nur die Tertiärstapelfaserschicht mit den Sekundärstapelfasern auszustatten und die Mikrofaserschicht ohne Sekundärfasern daran heranzuführen und durch eine Vernadelung der Schichten miteinander die Sekundärstapelfasern auch in die Mikrostapelfaserschicht, beziehungsweise -schichten, einzubringen.The preferred way of making one Cloth made of several layers of fleece provides, initially individual To form fleece layers and to connect them to one another. Each nonwoven layer can already be provided with the secondary staple fibers his. But it is also possible first only the tertiary staple fiber layer with the secondary staple fibers equip and the microfiber layer without secondary fibers to introduce it and by needling the layers together, the secondary staple fibers also in the micro-staple fiber layer or layers, contribute.

Die einzelnen Vliesschichten werden miteinander verbunden, was durch Vernadeln, Vennrirbeln oder Laminieren geschehen kann. Verfahren dieser Art sind an sich bekannt. Besonders gute Ergebnisse werden erreicht, wenn die Vliesschichten durch Punktverschweißen miteinander verbunden sind. Hierdurch ergibt sich eine durchbrochene Oberfläche, welche die Reinigungskraft des Tuches erhöht. Bei dem Punktverschweißen können die einzelnen Vliesschichten durch Verschmelzungszonen unter Anwendung von Wärme und Druck verfestigt sein. Es ist aber auch möglich, die Oberflächen des Reinigungstuches durch Verschmelzungszonen, insbesondere durch Kalandrieren, zu verfestigen.The individual fleece layers are connected with each other, by needling, rubbing or laminating can happen. Methods of this type are known per se. Especially Good results are achieved if the fleece layers are spot welded together are connected. This results in an openwork surface, which the cleaning power of the cloth increases. With spot welding, the individual layers of fleece through fusion zones using of warmth and pressure have solidified. But it is also possible to change the surface of the Cleaning cloth through fusion zones, especially by calendering, to solidify.

Das Flächengewicht des Reinigungstuches beträgt in der Regel 75 bis 250 g/qm vorzugsweise 120 bis 180 g/qm. Bei einem dreilagigen Reinigungstuch aus einer Mittelschicht aus Tertiärstapelfasern und Sekundärstapelfasern und zwei Deckschichten aus Mikrostapelfasern und Sekundärstapelfasern wird das Flächengewicht der Mittelschicht so gewählt, daß es 40 bis 80 % des Gesamtflächengewichts beträgt. Dabei ist es günstig, wenn die Flächengewichte der Deckschichten gleich sind.The weight per unit area of the cleaning cloth is Rule 75 to 250 gsm, preferably 120 to 180 gsm. With a three-layer Cleaning cloth made of a middle layer of tertiary staple fibers and secondary staple fibers and two cover layers made of micro-staple fibers and secondary staple fibers the basis weight the middle class so chosen that it 40 to 80% of the total basis weight is. It is convenient if the basis weights the cover layers are the same.

Der Anteil an Mikrostapelfasern in der beziehungsweise den Deckschichten überwiegt den Anteil an Sekundärstapelfasern. Der Anteil an Mikrostapelfasern liegt zwischen 70 und 98 %, bevorzugt zwischen 70 und 80 %.The proportion of micro staple fibers in the top layer or layers predominates the proportion of secondary staple fibers. The proportion of micro staple fibers is between 70 and 98%, preferably between 70 and 80%.

In der Mittelschicht überwiegt der Anteil an Sekundärstapelfasern den Anteil an Tertierstapelfasern. Er beträgt zwischen 70 und 100 %, vorzugsweise 70 und 80 %.It predominates in the middle class the proportion of secondary staple fibers the percentage of staple fibers. It is between 70 and 100%, preferably 70 and 80%.

Ausführung der ErfindungExecution of the invention

Anhand von zwei in der Zeichnung dargestellten Ausführungsbeispielen wird die Erfindung näher erläutert.Using two in the drawing illustrated embodiments the invention becomes closer explained.

Es zeigt:It shows:

1 stark vergrößert einen Ausschnitt aus einem Reinigungstuch mit drei Vliesschichten im Schnitt und 1 greatly enlarges a section of a cleaning cloth with three layers of fleece in the cut and

2 einen Ausschnitt aus einem Reinigungstuch aus drei miteinander durch Punktverschweißen verbundenen Vliesschichten im Schnitt. 2 a section of a cleaning cloth from three non-woven layers connected by spot welding in section.

Ausführung der ErfindungImplementation of the invention

In der 1 ist vergrößert ein Schnitt durch ein Ausschnitt eines Reinigungstuches 1 gezeigt, welches aus drei Vliesstoffschichten A, B, A gebildet ist. Die Mittelschicht B besteht aus synthetischen Tertierstapelfasern vermischt mit Sekundärstapelfasern, während die beiden Deckschichten A, A aus Mikrostapelfasern und Sekundärstapelfasern gebildet sind. Die beiden Deckschichten A, A sind in ihrer Zusammensetzung gleich. Die Vliesstoffschichten A, B, A sind wasserstrahlvernadelt. Die einzelnen Fasern werden dadurch miteinander verknäult und die Mikrostapelfasern zumindest teilweise gesplittet. Es entsteht ein fester Verbund der verschiedenen Fasern und Vliesschichten miteinander.In the 1 is enlarged a section through a section of a cleaning cloth 1 shown, which is formed from three nonwoven layers A, B, A. The middle layer B consists of synthetic tertiary staple fibers mixed with secondary staple fibers, while the two outer layers A, A are formed from micro-staple fibers and secondary staple fibers. The two cover layers A, A are in their closed composition the same. The nonwoven layers A, B, A are needled with water jets. The individual fibers are thereby knotted together and the micro-staple fibers are at least partially split. This creates a firm bond between the different fibers and nonwoven layers.

In der 2 ist ein Ausschnitt eines dreischichtigen Reinigungstuches 2 ebenfalls im Schnitt gezeigt. Die drei Vliesstoffschichten A, B, A haben den gleichen Aufbau wie die Schichten A, B, A der 1. Die Schichten sind jedoch punktverschweißt an musterartig vorgegebenen Stellen 3. Dadurch ergibt sich eine höhere Reinigungswirkung des Tuches 2. Das Punktverschweißen wird durch eine Kalandrierung der Vliesschichten erreicht, indem die Vliesschichten gemeinsam durch zwei Walzen hindurchgeführt werden, von denen eine mit musterartig verteilten Noppen versehen ist und die andere eine glatte Oberfläche hat. Daraus resultieren die einseitigen Verschmelzungszonen der Vliesschichten A, B, A an den Stellen 3 des Tuches 2. Durch diese Maßnahme werden die einzelnen Schichten A, B, A fest miteinander verbunden und außerdem die thermoplastischen Fasern der einzelnen Schichten, zumindest an der Tuchoberfläche durch die erhitzten Walzen miteinander verklebt und dadurch die Sekundärstapelfasern miteingeschlossen. Die Vliesschichten A, B, A werden vor ihrer Kalandrierung wasserstrahlvernadelt, um so eine besonders starke Verbindung der Fasern und Schichten untereinander zu erreichen. Außerdem werden die Mikrostapelfasern während der Wasserstrahlbehandlung gesplittet.In the 2 is a section of a three-layer cleaning cloth 2 also shown in section. The three nonwoven layers A, B, A have the same structure as layers A, B, A 1 , However, the layers are spot-welded at predetermined locations 3 , This results in a higher cleaning effect of the cloth 2 , The spot welding is achieved by calendering the nonwoven layers by passing the nonwoven layers together through two rollers, one of which is provided with patterned knobs and the other has a smooth surface. This results in the one-sided fusion zones of the fleece layers A, B, A at the points 3 of the cloth 2 , As a result of this measure, the individual layers A, B, A are firmly connected to one another and, moreover, the thermoplastic fibers of the individual layers are bonded to one another, at least on the surface of the cloth, by the heated rollers, thereby including the secondary staple fibers. The fleece layers A, B, A are needled with water jet before they are calendered in order to achieve a particularly strong bond between the fibers and layers. In addition, the micro-staple fibers are split during the water jet treatment.
